Bio Signal Conditioning and Processing For Biological Real Time Applications Using Mixed Signal Processor
In medical and health care applications it was always desirable to perform pre-processing and conditioning on the sensor raw output before data acquisition. Based on this requirement, biosensor was proposed and designed using conducting polymers and nano - materials which was having In- situ Signal Conditioning Electronics that eliminates need for additional on board hardware circuitry. This advanced signal-conditioning circuit mainly consists of an ASIC with associated components that process the raw output from bio-sensor. The ASIC works with lowvoltage and low-current, with wide operating temperature range. The bio-sensor, which was designed very much sensitive to room temperature and pressure. Nano-bio sensor ASIC operates at +5V input and provides an output of 0 to 500 mV for absolute sensor output of 0 to 500 nano-amps or pico-amps. READ..
